36274	MigrationWriter does not support writing run_before	Mikuláš Poul	Mikuláš Poul	The `MigrationWriter` class implements writing a instance of `django.db.migrations.migration.Migration`. It supports serializing all the options it could have except for `run_before`. I recently made a PR for a third-party package on remaking migrations (a form of squashing), and had to subclass the writer to be able to include `run_before`. I think `MigrationWriter` should support all options available on `Migration`, to make working with migrations easier.
